IMPROVEMENT IN NURSING-BOTTLES.

Specification forming part of Letters Patent No. 197,

April 13, 1877.

To all whom it may concern:

Be it known that I, Lunwre MEYER, of the cityof Berlin, Prussia, Germany, have invented a new and Improved Nursing-Bottle, which invention is fully set forth in the following specification, reference being had to the accompanying drawing, in which Figure 1 shows a front elevation of the bottle; Fig. 2, a vertical section in the line a b Fig.3, aportion of the same section, enlarged; Fig. 4, a horizontal section in the line 0 d.

The object of my invention is to construct a simple and convenient apparatus for determining the right temperature of the nursingfluid in a nursing-bottle; and it consists in a novel combination of a thermometer with a singularly-formed nursing-bottle.

For this purpose I have cast or formed the glass bottle A with a shallow longitudinal'indentation, B, along one of its straight sides, the lower end D of which indentation is enlarged wide and deep enough to receive the bulb G of a thermometer, the pipe of which is bent, and lies snugly in the indentation B, so as not to protrude above the surface of the bottle.

In the center of the enlargement D is provided a hole or vent, E, as a connnunication between the inside of the bottle A and the bulb O of the thermometer.

For the purpose of securing the thermometer to its place, a shield, F, of any suitable material, and fitting loosely in the mouth of the enlargement D, is pressed to the bulb 0 by a rubber band, G, encircling the bottle A in an annular indentation, and drawn through or fastened to the shield F in such way that it forms a cushion between the shield F and t-11e $".:P and, to prevent any leakage, a rubber washer is arranged between the bulb G and the bottom of the enlargement D, which does not prevent the fluid in the bottle A comin, contact with the bulb (3.

The rubber band Gr may be formed in ring-shaped piece, or, as shown in the draw with its ends hooked together by a clam lock.

To simplify the use of the apparatus, the available highest and lowest tempera is marked on the bottle A at f and g.

The band G, with the shield F, the mometer, and the rubber washer, can be e removed for cleaning the bottle A, and as easily applied to it and adjusted for u! the most inexperienced nurse.

It is evident that the rubber band G the shield F may be varied in shape or 1 rial, as may be the bottle itself.

I know that the combination of a then eter and a nursing-bottle is not new; it was before effected only in such m: that the removal of the thermometer for in gpurposeswas very difficult and trouble causing, in most cases, the breaking c thermometer. It is the very handy rem and fixing back to its place of the latter is the object I have accomplished by n V100.

What I claim is The combination of a nursing-bottle structed with suitable recesses, and i vent-hole, and a thermometer, and the F, and a rubber band, G, or its equii substantially in the manner shown, and purpose set forth.

This specification signed by me this '5 of March, 1877.
